Multi-protocol ANT System-on-Chip
ANT System-on-Chip
The nRF51422 is a powerful multi-protocol single chip solution
for ULP wireless applications. It incorporates Nordic’s latest
best-in-class performance radio transceiver architecture, the
ARM Cortex M0 MCU and 256kB flash memory. The nRF51422
supports an ANT+ and Gazell protocol stacks.

Lower power and higher performance
The nRF51422 uses the 32-bit ARM Cortex M0 MCU, together
with extensive flash availability, 256kB in total, +12kB RAM
available for application development. Code density and execution
speed are considerably greater than for 8/16-bit platforms.
The Programmable Peripheral Interconnect (PPI) provides a
16-channel bus for direct and autonomous system peripheral
communication without CPU intervention. This brings predictable
latency times for peripheral to peripheral task and events and
associated power saving benefits. The device has 2 global power
modes ON/OFF, but all system blocks and peripherals have
individual power management control which allows for automatic
switching RUN/IDLE for system based only on those required/not
required to achieve particular tasks.
The new radio forms the basis of the nRF51422’s performance.
The radio supports ANT and is on-air-compatible with the
nRF24L/nRF24AP-series products from Nordic Semiconductor.
Output power is now scalable from a maximum of +4dBm down
to -20dBm in 4dB steps. Sensitivity is increased at every level
and offers sensitivity ranges (dependent on data rate) from -96 to
-85dBm, with -90dBm for 1Mbs ANT.
